How do you find which process is taking how much cpu?

The task manager or the Resource monitor

Explanation:

In most windows Operating System platforms, the task manager helps us determine what process is taking how much CPU. Your PC is required to run flawlessly but sometimes, for some reasons, it fails to do so. It might slow down completely due to some processes hogging the CPU up. To be able to find out about those processes, you can use the task manager. The task manager is built-in and serves as a monitoring tool for all apps, processes and services that run concurrently with one another
